OUT
remote sense, negative node input, connected to the
-ve load point
Standby voltage output
Standby voltage, return, tied internally to Output Return
Active load sharing bus
Input AC Voltage “OK” signal output (Internal pull up is
10kΩ to Vsb)
Power good signal output (Internal pull up is 10kΩ to Vsb)
Floating pin will turn off P/S (shorter pin, last-make and
first-break contact for hot plugging). This signal overrides
PS-On in disabling the Main Output
Internally tied to Vsb return

Dotted lines show optional remote sense connections.
Optional remote sense lines can be attached to a load that is a distance
away from the power supply to improve regulation at the load.

CURRENT SHARING NOTES
12V Output: Current sharing is achieved using the active current share method. (See wiring diagram for connection details.)
The total combined load must be below 1600W at startup. Current sharing can be achieved with or without remote sense connected to the common load.
V_SB outputs can be tied together for redundancy but total combined output power must not exceed 20W. The V_SB output has internal ORing MOSFET for
additional redundancy / internal short protection.
The current share pin B1 is a connection between the two units. It is input and/or output as the voltage on the line controls the current share. A power
supply will respond to a change in this voltage but a power supply can also change the voltage depending on the load drawn from it. On a single unit this
would read 8V at 100% load. For two units sharing load then this should read 4V for perfect current sharing.
Up to 6 units can be paralleled together. Please consult your Murata sales representative if operation with more than six units in parallel is needed.
